Nichaya Thambulam (Engagement/Betrothal) is a Marriage ceremonial occasion in which the prospective bride and groom formally announce their relationship in the presence of both families.
On this day, the wedding date is usually finalized.
After the engagement, the Muhurtha pathirikai (auspicious wedding date document) should be prepared.
While preparing the Muhurtha pathirikai, all four corners should be applied with turmeric, especially from the bottom upwards, as it is considered auspicious.
